Re: [Linux-uvc-devel] V4L software with linux-uvc?
Hi Rene, I'm successfully using Logitech QuickCam for Notebooks Pro on two Gentoo machines with with Linux-UVC and V4L2 (e.g. Ekiga). But as a lot of applications haven't been ported to V4L2, yet (Adobe Flash Player, Sane-Backends, ...) I'm looking for a way to emulate an V4L1 device. Is there any way to do this with linux-uvc? V4L2 provides a V4L1 compatibility layer. I haven't heard about anyone getting it working with the UVC driver, so it will probably not be easy.

Re: [Linux-uvc-devel] poll() and read() standard system calls
Hi Luca, after having had a rapid look at UVC driver internals, I saw that the read() system call has not been implemented yet, while poll() is implemented and can be called from userspace. Apart from the V4L2 API, given that poll() is a standard system call and is supposed to be closely tied to non-blocking reads() to provide a _standard_ I/O mechanism for retrieving data, are there any reasons for not providing read() as well together with poll(), as it's probably confusing to have partial support for this I/O interface? The only reason why read() hasn't been implemented (yet) is that mmap() has been implemented first, and there hasn't been any demand for read(). It's on my todo list though. poll() without read() makes sense, using VIDIOC_DQBUF.

Re: [Linux-uvc-devel] QuickCam Fusion lockup
Laurent, I have recently recompiled the lastest EKIGA which now seems to be working pretty well with my Fusion webcam. I have stopped and started it many times without experiencing problems. (it used to happen every 3-4 times). Anyway, something for your thought processes:),I got the lockout last night and just decided to shutdown ekiga and go to bed. When I tried Ekiga the next morning to get the error messages, it worked! To emphasize I did nothing in between. Did not reset the usb or power off the pc etc. It has to be a timeout issue somewhere? Thanks for a very usable driver.
